Well, before I start I have to confess that I liked Kasumi Alpha in DOA Dimensions... a lot. (played her more than I played the original). I was actually saddened when they morphed her into that jello-monster known as Alpha-152, mainly because I sorta liked the whole "I'm gonna steal Hayate and your life all for myself" bit her normal, yet immature self had against Kasumi. Now, that being said... I'm REALLY digging the upgraded Alpha, mainly from a gameplay perspective since I actually DO play the game against others online instead of just the ryona content. Girl's crazy fast and captures the kind of stylish combo set I like with the teleport shenanigans. They also did a good job so far trying to give her her own unique playstyle with a nice fusion of Kasumi, 152, and I think I saw some Hayate & Hayabusa influences in there too. And I have to say, at the very least I'm glad she retains the previous Alpha's red and black ninja garbs as alts. I love those a lot more than the new cloak ATM. I hope she gets her own set of DLC outfits that resemble her outside of just fighting garbs though (I'm a sucker for casual clothes no matter who wears them).
My only gripe so far is that she most likely will completely have Kasumi's in-game vocals to the T instead of having her own individual vocal script (I know this clone by story is supposed to mimic the original Kasumi much more accurately, but I still liked the fact Dimensions' Alpha had her own individual voicing [from her original JPN VA no less])
Just know, Phase-4's joining the current location test today, so you'll probably see more low-quality videos peaking up on the net just like Marie Rose had before. Looking forward to checking her out further.
